Description

<Desc / Clms Page number 1>

 The invention relates to an anhydrous deodorant cosmetic composition comprising: at least one deodorant active agent; at least one gel (A) formed from at least one hydrocarbon oil and at least one copolymer or a mixture of di-, tri-, multi- or radial block copolymers composed of monomeric styrene and thermoplastic monomer or co-monomer segments; at least one silicone gel (B) formed from at least one partially or fully crosslinked solid elastomeric organopolysiloxane and at least one hydrocarbon oil and / or a silicone oil and / or a fluorinated oil.

Many different types of nonaqueous (anhydrous) deodorant compositions have been described in the literature and have appeared on the market in such forms as gels, sticks, creams, roll-ons or aerosols.

Among the deodorant anhydrous creams, there are two main types of formulations: wax-based formulations and fat-based thickener formulations.

The formulations based on waxes have been described in particular in the patent application WO97 / 16162. This type of product requires a complex manufacturing process. The heating of waxes and their destructuring are indispensable; This entails numerous constraints related, inter alia, to the casting temperature and the shear forces required for the preparation of these formulations.

The formulations based on thickeners of the fatty phase have been described in particular in US Pat. No. 5,069,897. Their manufacture is simple since it does not require specific heating or agitation. However, this type of product has significant exudation phenomena.

Thus, one seeks deodorant anhydrous creams ever more efficient in terms of stability, homogeneity, and good rheological properties to the application. Said compositions must also leave no visible residue (white) on the skin on application or after drying of the composition after application, while leaving skin soft to the touch and a nongras effect.

After much research conducted on the subject, the Applicant has now discovered, unexpectedly and surprisingly, that by introducing into a deodorant cosmetic composition, a gel (A) formed from a hydrocarbon oil and at least one block copolymer based on a styrene monomer and a thermoplastic monomer or co-monomer and a silicone gel (B) formed from at least one fluorinated or fluorinated hydrocarbon oil and at least one solid organopolysiloxane elastomer partially or completely crosslinked, it was possible to significantly improve the compositions and to obtain at the same time the desired properties, ie stable and homogeneous compositions, of viscosity in agreement with the desired forms of presentation (creams), which do not exude not, spread very well on the skin, without leaving a visible residue white and / or greasy on application or after drying after application.

This discovery is the basis of the present invention.

The present invention thus firstly relates to an anhydrous deodorant cosmetic composition comprising: at least one deodorant active agent; at least one gel (A) formed from at least one hydrocarbon oil and at least one copolymer or a mixture of di-, tri-, multi- or radial block copolymers composed of monomeric styrene-type segments and thermoplastic monomer or co-monomer segments; at least one silicone gel (B) formed from at least one partially or fully crosslinked solid elastomeric organopolysiloxane and at least one hydrocarbon oil and / or a silicone oil and / or a fluorinated oil.
